Mario Gotze landed in trouble this summer when he was formally unveiled as a Bayern Munich player, choosing to wear Nike clothing when the German champions are sponsored and even partly owned by Adidas.

The pictures led to a public apology to Adidas from Bayern Munich, as per Eurosport, and there was even a €20,000 fine issued for the gaffe.

Gotze doesn't appear to have learned his lesson, though (or perhaps he wasn't really trying to), because this week he has been spotted in Nike socks on duty for the all-Adidas Germany national side.

Once again, there has been a debate about it in his homeland, with German national team PR manager Oliver Bierhoff telling Bild (via Dirty Tackle blog):

There is only free shoe choice for us. Otherwise, we are naturally committed to our partners. Although we do not have employment contracts with the players, we strongly suggest guidelines to make the importance clear to them and show community spirit. Finally, the sponsors are committed to a high degree, not only economically. So such actions should be excluded.

Gotze was back in Adidas socks soon after the picture above was taken (with Nike boots, of course).
